MORRIS E. WARE, OF PHILADELPHIA, PENNSYLVANIA.

BUSH-HAMMER.

SPECIFICATION forming part of Letters Patent No. 439,219, dated October28, 1890.

Application filed September 2, 1890- Serial No. 363,787. (No model.)

To all whom it may concern.-

V Be it known that I, MORRIS E. WARE, a citi zen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inBush-Hammers; andI do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which itappertains to make and use the same.

My invention has relation to bush-hammers; and it has for its object acheap, durable, and eificient construction of hammer, wherein the bushescan be relatively adjusted to one another to take up the wear of any oneof them.

My invention accordingly consists of the combinations, constructions,and arrangements of parts, as hereinafter more particularly described inthe specification, and pointed out in the claims, reference being had tothe accompanying drawings, wherein Figure 1 is a horizontal section,partly in plan, of the hammer embodying my improvements. Fig. 2 is a topView of the hammer; Fig. 3, a side elevation, and Fig. 4 is a plan ofone of the bushes detached from the hammer.

A represents the head of the hammer, having central handle-opening a andend sockets or recesses a for the bushes B. The sockets a are bounded bythe bottom and side ends a and a of the hammer-head, so that said partsare all formed in one piece, to increase the strength of the head andavoid bolt 01' other connections therefor when said ends a and a aremade separate from and secured to the hammer-head. The top parts of therecesses or sockets a are open; but these openings are closed byremovable top plates 0, which have side lugs c fitting intocorresponding recesses c in the top edges of the sides a of the socketsa, as more plainly shown in Fig. 2.

The bushes B are provided with two elongated holes 12 bin the directionof the length of the bushes, and these holes I) may be parallel to eachother, as shown. Through these holes I) and through circular andsnugly-fitting openings at in the socket-bottoms a and correspondingopenings 0 in plates 0 pass bolts D, with, preferably, screw-nuts d atone end to fasten the plates 0 and the bushes to the hammer-head.

From the foregoing it will be noted that as the hammer-head has thebottoms and sides of the sockets Ct formed in one piece and the plates 0have lug-connections with said head and are, together with the bushes B,bolted to the head the bushes are firmly maintained in-position and astrong, durable, and eificient hammer is provided, the bushes whereofare readily inserted in position and when worn out can becorrespondingly removed and replaced with others. The elongatedopenings 1) in the bushes admit of the same being adjusted to make theirworking or cutting edges come flush with one another, and in case one ormore bushes of a nest wear more rapidly than the others by loosening thebolts D therefor the worn bush can be dropped down or adjusted to bringits working-edge flush with those of the remaining bush.

What I claim is- 1. Abush-hammer head A, having its socket sides a andbottoms a formed in one piece, in combination with the plates 0, havinglug-connections c with said socket sides, bushes B, having elongatedopenings b, and fastening-bolts D, substantially as set forth.

2. The combination of a bush-hammer A, having integrally-formed endsockets a, with open tops, plates 0, having lugs c fitting openings inthe side walls of the sockets, bushes B, and fastening screws or boltsD,

substantially as set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
